METHOD FOR BIOLOGICAL PURIFICATION OF WASTE WATER BY THE ACTIVATED SLUDGE METHOD AND APPARATUS FOR CARRYING OUT THE METHOD |
摘要 |
A method and an apparatus for biological purification of waste water by the activated sludge method, whereby the waste water is continuously passed through several treatment zones in which the waste water is successively subjected to nitrification and denitrification, and which are arranged circularly around a supply zone for waste water, whereby the supply zone is alternatingly connected with one of the treatment zones, and optionally a clarification zone for dividing the treated waste water into a water fraction and a sludge fraction.
